A source has exclusively confirmed to Access Hollywood that the two musicians – who faced off in an infamous incident at last year's MTV Video Music Awards — will be among those participating in Quincy Jones' remake of the 1985 charity anthem, "We Are The World," at a recording session the day after the Grammys.

Quincy, himself, recently spoke out on the re-recording to E! Online, stating, "It's the 25th anniversary and it's perfect timing…It's not an accident, man. That's God. It will be 'We Are The World' for Haiti."

The 1985 track, recorded to provide humanitarian aid to Africa, was written by Michael Jackson and Lionel Richie and also featured performances by the likes of Stevie Wonder, Ray Charles, Paul Simon, Bruce Springsteen, Bob Dylan, Tina Turner and Diana Ross, among others.

The news of a possible remake was first reported by The Hollywood Reporter's Showbiz 411 earlier this month.

According to E!, other potential performers on the track include Jennifer Hudson, Will Smith, Jason Mraz, Sheryl Crow, Mya and Justin Bieber, though Quincy said it's still in the works.

"I want to get a final list before I put it out," Quincy said.

And with Michael Jackson in mind, Quincy told the site he plans to discuss his relationship with the late King of Pop in a CNN special, though he is not participating in the planned Grammy tribute to the singer.

A number of musicians have contributed to Haiti relief already, with the "Hope For Haiti Now" digital album hitting No. 1 on the Billboard charts this week – the first digital-only compilation to do so.
